Cell phone facts and statistics

GAO says more research needed

"According to FDA and others, the research to date does not show that mobile phone radiofrequency emissions have adverse health effects but there is not enough information at this point to conclude that these products are not without risk. While most epidemiological and laboratory studies related to the radiofrequency emissions of mobile phones have found no adverse health effects, the results of some studies have raised questions that require further research."

How much power does a cell phone use?

A mobile phone is designed to operate at a maximum power level of 0.6 watts. A household microwave oven uses between 600 and 1,100 watts.

Cell phone usage explodes

Cell phone usage

In 1994, 16 million Americans subscribed to cellular phone services. Today, more than 110 million Americans are subscribers. Some experts predict that worldwide subscribership will reach 1.2 billion people by 2005.

Brain cancer is on the rise

The incidence of brain cancer has increased 25% since 1973, according to the National Cancer Institute. Each year, 185,000 Americans will be diagnosed with a primary or metastatic brain tumor, according to the National Brain Tumor Foundation.

How to check for emission levels

The Cellular Telecommunications and Internet Association decided last year that all CTIA-certified cell phones must have their radiofrequency emission levels made available to consumers. The problem is that the information is usually noted inside the box in which the phone is sold, so anyone who wants to compare levels needs to ask a store clerk to open multiple boxes.

You can get the rating for a specific cell phone at the Federal Communications Commission Web site if you have the FCC identification number for the phone and if the phone is new enough to be listed.

Patent filings raise questions
Even as major cell phone manufacturers argued that phones pose no health risks, the companies were filing patents for devices designed to protect users from radiation emitted by the phones.

Scientific studies are a mixed bag
Research into the safety of cellular phones has resulted in some studies that show no adverse effects, and others that raise questions.

Forum: Cell-phone risks
Discuss them with Dr. George Carlo, former director of the cellular industry's research effort on them.
